High-temperature heat storage and evaporation integrated device

Abstract

The invention discloses a high-temperature heat storage and evaporation integrated device, which comprises a heat storage block (5), a liquid storage tank (7), a heat insulation layer (4), a heating pipe (8) and an evaporation pipe (9). The heat insulation layer (4) is tightly attached to the outer wall of the liquid storage tank (7); the heat storage block (5) is placed in the liquid storage tank (7); a plurality of through holes are regularly distributed on the heat storage block (5) at equal intervals; and the heating pipe (8) and the evaporation pipe (9) alternately pass through the through holes on the heat storage block (5). The heating pipe (8) and the evaporation pipe (9) are light pipes or reinforced heat exchange pipes; and a high-temperature heat transfer working medium is filled in the container of the liquid storage tank (7).

Description

technical field [0001] The invention relates to a heat storage and evaporation integrated device. Background technique [0002] Since a continuous and stable power supply can be achieved through heat storage, concentrating solar thermal power generation is recognized by countries all over the world as a renewable energy power generation technology with great potential. The heat storage method as well as the performance and cost of heat storage materials are of great importance to the construction and operation costs of solar thermal power plants. Heat storage materials used in solar thermal power generation systems need to have the following characteristics: high energy storage density; heat storage materials and heat exchange liquids should have good heat exchange performance; heat storage materials should have good stability; heat storage materials There should be good chemical compatibility with the system equipment; the heat storage and release cycle should be reversibl...

Problems solved by technology

Chinese patent ZL200610112004.4 proposes a high-temperature heat storage and heat storage method using concrete, and uses gravity heat pipes to solve corrosion and freezing problems. However, the expansion rate of metal pipes and concrete is different, and thermal expansion and contraction will cause cracks in the concrete structure. The contact thermal resistance between the metal pipe and the concrete is also large

In the way of heat storage and steam generation, the cost can not be further greatly reduced, and the system efficiency and stability can be improved.
